Manual setup (git clone)
```bash
git clone --recurse-submodules git@github.com:flitzrrr/agent-skills.git

## Architecture
```
agent-skills/
skills/ 504 entries (symlinks to vendor + local forks)
vendor/ 20 Git submodules (upstream sources)
bin/ CLI and build scripts
docs/ GitHub Pages catalog and project documentation
.github/ CI workflows and copilot-instructions.md
```
Skills are exposed as a flat directory under `skills/`. Most entries are symlinks into `vendor/` submodules. Skills with local extensions (e.g., `execute-work-package` with multi-transport support) are maintained as real directories alongside the symlinks.
### Naming Convention
Skills are namespaced by source to avoid collisions: `anthropic-pdf`, `tob-static-analysis`, `cloudflare-wrangler`, `terraform-code-generation`, `scientific-bioinformatics`, `aws-lambda`, `finance-equity-research`, `callstack-react-native-best-practices`. Sentry and marketing skills are un-prefixed (`code-review`, `content-strategy`).
### Automation
| Workflow | Trigger | Purpose |
| --- | --- | --- |
| [Skill Discovery](.github/workflows/skill-discovery.yml) | Weekly | Find trending skill repos, security-scan, auto-add |
| [Submodule Update](.github/workflows/submodule-update.yml) | Weekly | Pull upstream changes, open PR |
| [MegaLinter](.github/workflows/megalinter.yml) | Push / PR | Lint markdown, YAML, JSON |
| [npm Publish](.github/workflows/npm-publish.yml) | Tag `v*` | Publish to npm, create GitHub Release |

## MCP Execution Backend (l4l-oci)
The [execute-work-package](skills/execute-work-package) skill supports three transport modes for delegating implementation to a sub-agent:
| Transport | Mechanism | When to use |
| --- | --- | --- |
| **MCP via l4l-oci** (default) | [l4l-oci](https://github.com/DasDigitaleMomentum/l4l-oci) exposes 10 MCP tools for the gated blueprint-gate-execute lifecycle | Any IDE with MCP support |
| **Fresh Agent** | IDE spawns a new sub-agent per step (no external server) | Fallback when l4l-oci is not configured |
| **Stateful Session** | Sub-agent session resumed across steps | OpenCode only |
When l4l-oci MCP tools are available (`create_handle`, `generate_blueprint`, `submit_gate`, `execute_handle`, `get_digest`), the skill uses them automatically. The bundled `scripts/start-l4l-oci.sh` auto-starts the server if needed. See the [l4l-oci setup guide](https://github.com/DasDigitaleMomentum/l4l-oci/blob/main/docs/setup.md) for configuration.
